This is the gray version of the same game seen previously on this list. The gray version is much more common but still sells for a premium price.

During the competition Nintendo gave away Gray versions of the game to winners at each of the preliminary locations and in each of the three age groups. That would account for 90 of these cartridges. Each cartridge has a number on it and the numbers go much higher than 90 so collectors think there might be more than 90 in existence.
